In the present study high efficiency Agrobacterium tumefaciens mediated transformation system of wheat (Triticum aestivum L.) cv. Inqilab-91 was developed by exploiting bacterial culture density and acetosyringone concentration. Agrobacterium strain EHA101 harboring binary vector pIG121Hm, containing gene for GUS activity and hygromycin resistance was used in transformation experiments. Differe...
this thesis deals essentially (but not from all aspects) with the extension of the notion of semigroup compactification and the construction of a general theory of semitopological nonaffine (affine) transformation semigroup compactifications. it determines those compactification which are universal with respect to some algebric or topological properties. as an application of the theory, it is i...
Many bacteria are highly sexual, but the reasons for their promiscuity remain obscure. Did bacterial sex evolve to maximize diversity and facilitate adaptation in a changing world, or does it instead help to retain the bacterial functions that work right now? In other words, is bacterial sex innovative or conservative? Our aim in this review is to integrate experimental, bioinformatic and theor...
Nowadays, genetic engineering methods are able to reduce the time of breeding programs for improvement of fruit trees, as well as offering a focused breeding system. The purpose of the present investigation was to study the factors that affect Agrobacterium tumefacience mediated transformation of two pear cultivars: Bartlett and Harrow Delight. Two explants (leaves and axillary shoot meristems)...
Horizontal gene transfer plays a significant role in bacterial evolution and has major clinical importance. Thus, it is vital to understand the mechanisms and kinetics of genetic transformations. Natural transformation is the driving mechanism for horizontal gene transfer in diverse genera of bacteria. Our study introduces a simple and rapid method for the investigation of natural transformatio...
Bacterial competent cells are essential for cloning, construction of DNA libraries, and mutagenesis in every molecular biology laboratory. Among various transformation methods, electroporation is found to own the best transformation efficiency. Previous electroporation methods are based on washing and electroporating the bacterial cells in ice-cold condition that make them fragile and prone to ...
